Detailed Explanation of the Method for Raising Jujube Seedlings by Root Cutting and Returning to the Nursery
To raise jujube seedlings by root cutting and returning them to the nursery, first select plants of excellent quality and free from pests and diseases as mother plants. Before budbreak, dig a trench 30-40 cm wide and 40-50 cm deep around the outer edge of the mother plant's canopy to cut the jujube roots, and use scissors to trim the cut root wounds smooth. Apply decomposed organic fertilizer, about 75 kg per plant, mix it with moist soil, fill it into the trench and tread it firm. If conditions permit, it is best to irrigate thoroughly once. Then cover with a layer of loose soil to conserve moisture. After the jujube roots are stimulated, a large number of clustered root-sucker seedlings will appear on the ground near the trench in May-June. Management of the root-sucker seedlings should be strengthened in a timely manner. After budbreak, remove excess buds; the principle is to remove the dense and keep the sparse, and remove the weak and keep the strong, generally with a plant spacing of about 15 cm, so as to ensure normal growth of the seedlings.

A New Method of Grafting Jujube Trees: A Detailed Guide to the Chip Budding Technique
Chip budding jujube trees is a good method for developing fine jujube varieties. It is introduced as follows: 1. Tools: pruning shears, grafting knife, plastic strips. 2. Collection and storage of scions. ① Spring-summer grafting: (late April to late June), before the end of March, collect well-developed, pest-free one-year-old jujube head branches from a mother tree orchard of fine varieties, cut off the secondary branches (leaving 2 cm), store them in a cool, moist place, bury them well in moist sand, or store them in a cellar less than 4 m deep or suspend them down a well (below 7°C). In this way the scions can be stored until late June to early July. ② Autumn grafting: (early August to mid-to-late September) collect current-year lignified branches, immediately remove the secondary branches and leaves, and use them as soon as they are collected. If they need to be stored for a short time, they can be placed in a container holding 10 cm of clean water and suspended down a well 0.5-1 m above the water surface or placed in a cellar.
